Cost Analysis of Pelvic Exenteration Surgery for Advanced Pelvic Malignancy.

BACKGROUND: Pelvic exenteration (PE) is a radical procedure involving multi-visceral resection for locally advanced pelvic malignancies. Such radical surgery is associated with prolonged operating theater time and hospital stay, as well as a substantial risk of postoperative complications, and therefore significant financial cost. This study aimed to comprehensively detail the inpatient cost of PE at a specialist center in the Australian public sector. METHODS: A retrospective costing review of consecutive PE operations at Royal Prince Alfred Hospital in Sydney between March 2014 and June 2022 was performed. Clinical data were extracted from a prospectively maintained database, and in-hospital costing data were provided by the hospital Performance Unit. All statistical analyses were performed using SPSS. RESULTS: Pelvic exenteration was performed for 461 patients, of whom 283 (61 %) had primary or recurrent rectal cancer, 160 (35 %) had primary or recurrent non-rectal cancer, and 18 (4 %) had a benign indication. The median admission cost was $108,259.4 ($86,620.8-$144,429.3) (Australian dollars [AUD]), with the highest costs for staffing followed by the operating room. Overall, admission costs were higher for complete PE (p < 0.001), PE combined with cytoreductive surgery (CRS) (p < 0.001), and older patients (p = 0.006). DISCUSSION: The total admission cost for patients undergoing PE reflects the complexity of the procedure and the multidisciplinary requirement. Patients of advanced age undergoing complete PE and PE combined with CRS incurred greater costs, but the requirement of a sacrectomy, vertical rectus abdominal flap reconstruction, major nerve or vascular excision, or repair were not associated with higher overall cost in the multivariate analysis.

Patient-Reported Outcomes in Chinese Patients with Locally Advanced or Recurrent Colorectal Cancer After Pelvic Exenteration.

BACKGROUND: Pelvic exenteration (PE) is often the only curative treatment option for selected locally advanced and locally recurrent colorectal cancer associated with significant morbidity. Open and laparoscopic approaches were accepted for this procedure. OBJECTIVE: This study aimed to examine the Chinese patient-reported outcomes (PROs) and health-related quality of life (HRQoL) after PE. METHODS: A total of 122 enrolled participants were asked to complete PROs at baseline and 1, 3, 6, 9 and 12 months after PE. PROs included seven symptoms from the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). The HRQoL was assessed using the Functional Assessment of Cancer Therapy-Colorectal (FACT-C). RESULTS: The overall postoperative complication rate was 41.0%. Patients experienced lower physical and functional well-being and FACT-C 1 month after surgery, then gradually recovered. The FACT-C score returned to baseline 9 months after surgery. Social and emotional well-being did not show signs of recovery until 6 months after the surgical procedure, and did not fully return to baseline until 12 months post-surgery. Symptom rates of insomnia, anxiety, discouragement, and sadness (composite score >0) did not improve significantly from baseline until 12 months after surgery. CONCLUSIONS: PE is a feasible treatment choice for locally advanced primary and recurrent colorectal cancer. Social, psychological, and emotional recovery in the Chinese population after PE tends to be slower compared with the physical condition.

A systematic review and meta-analysis on mortality rate following total pelvic exenteration in cancer patients.

BACKGROUND: Total pelvic exenteration (TPE), an en bloc resection is an ultraradical operation for malignancies, and refers to the removal of organs inside the pelvis, including female reproductive organs, lower urological organs and involved parts of the digestive system. The aim of this meta-analysis is to estimate the intra-operative mortality, in-hospital mortality, 30- and 90-day mortality rate and overall mortality rate (MR) following TPE in colorectal, gynecological, urological, and miscellaneous cancers. METHODS: This is a systematic review and meta-analysis in which three international databases including Medline through PubMed, Scopus and Web of Science on November 2023 were searched. To screen and select relevant studies, retrieved articles were entered into Endnote software. The required information was extracted from the full text of the retrieved articles by the authors. Effect measures in this study was the intra-operative, in-hospital, and 90-day and overall MR following TPE. All analyzes are performed using Stata software version 16 (Stata Corp, College Station, TX). RESULTS: In this systematic review, 1751 primary studies retrieved, of which 98 articles (5343 cases) entered into this systematic review. The overall mortality rate was 30.57% in colorectal cancers, 25.5% in gynecological cancers and 12.42% in Miscellaneous. The highest rate of mortality is related to the overall mortality rate of colorectal cancers. The MR in open surgeries was higher than in minimally invasive surgeries, and also in primary advanced cancers, it was higher than in recurrent cancers. CONCLUSION: In conclusion, it can be said that performing TPE in a specialized surgical center with careful patient eligibility evaluation is a viable option for advanced malignancies of the pelvic organs.

Long-term outcomes of pelvic exenterations for gynecological malignancies: a single-center retrospective cohort study.

BACKGROUND: Recently, with the advancement of medical technology, the postoperative morbidity of pelvic exenteration (PE) has gradually decreased, and it has become a curative treatment option for some patients with recurrent gynecological malignancies. However, more evidence is still needed to support its efficacy. This study aimed to explore the safety and long-term survival outcome of PE and the feasibility of umbilical single-port laparoscopic PE for gynecologic malignancies in a single medical center in China. PATIENTS AND METHODS: PE for gynecological cancers except for ovarian cancer conducted by a single surgical team in Sun Yat-sen University Cancer Center between July 2014 and December 2019 were included and the data were retrospectively analyzed. RESULTS: Forty-one cases were included and median age at diagnosis was 53 years. Cervical cancer accounted for 87.8% of all cases, and most of them received prior treatment (95.1%). Sixteen procedures were performed in 2016 and before, and 25 after 2016. Three anterior PE were performed by umbilical single-site laparoscopy. The median operation time was 460 min, and the median estimated blood loss was 600 ml. There was no perioperative death. The years of the operations was significantly associated with the length of the operation time (P = 0.0018). The overall morbidity was 52.4%, while the severe complications rate was 19.0%. The most common complication was pelvic and abdominal infection. The years of surgery was also significantly associated with the occurrence of severe complication (P = 0.040). The median follow-up time was 55.8 months. The median disease-free survival (DFS) was 17.9 months, and the median overall survival (OS) was 25.3 months. The 5-year DFS was 28.5%, and the 5-year OS was 30.8%. CONCLUSION: PE is safe for patient who is selected by a multi-disciplinary treatment, and can be a curative treatment for some patients. PE demands a high level of experience from the surgical team. Umbilical single-port laparoscopy was a technically feasible approach for APE, meriting further investigation.

Postoperative venous thromboembolism after surgery for locally recurrent rectal cancer.

BACKGROUND: Local recurrence is common after curative resections of rectal cancer. Surgical resection is considered a primary curative treatment option for patients with locally recurrent rectal cancer (LRRC). LRRC often requires a combined resection of other organs, especially in the case of posterior recurrence, which requires a combined resection of the sacrum, making the surgery highly invasive. Venous thromboembolism (VTE) is one of the lethal complications in the postoperative period, particularly in the field of pelvic surgery. We found no reports regarding the risks of postoperative VTE in surgery for LRRC, a typical highly invasive procedure in the field of colorectal surgery. This study aims to evaluate the risk of postoperative VTE in surgery for LRRC patients. METHODS: From April 2010 to March 2022, a total of 166 patients underwent surgery for LRRC in the pelvic region at our institutions. Clinicopathological background and VTE incidence were compared retrospectively. RESULTS: Among the 166 patients included in the study, 55 patients (33.1%) needed sacral resection. Pharmacological prophylaxis for prevention of VTE was performed in 121 patients (73.3%), and the incidence of VTE was 9.09% (5/55 patients) among those who underwent surgery for LRRC with sacral resection, while it was 1.8% (2/111 patients) in those without sacral resection. In univariate analysis, the combination with sacral resection was identified as a risk factor for VTE in surgery for LRRC (p = 0.047). CONCLUSIONS: This study demonstrates that surgery for LRRC combined with sacral resection could be a significant risk factor for VTE.

Five-year quality-of-life assessment by urinary diversion type after pelvic Exenterations.

OBJECTIVE: To determine whether urinary diversion procedures performed at time of pelvic exenteration affect quality of life in patients with recurrent gynecologic malignancies. METHODS: We performed a retrospective secondary longitudinal analysis of quality of life according to type of urinary diversion patients received. Participants completed a series of validated questionnaires at various time points. We allocated patients based on urinary diversion type to either the continent group (CD; 29 [55 %]) or noncontinent group (NCD; 24 [45 %]). RESULTS: We noted a significant improvement in global health scores from baseline over time (time p = 0.027). Physical functioning scores showed a statistically significant difference over time (at 24 months: NCD, -4.3 [95 % CI, -14.1 to 5.4]; CD, 0.4 [95 % CI, -7.1 to 7.9]. p < 0.001). Social functioning scores were persistently higher for the CD vs NCD group at all time points but did not differ significantly between the groups at baseline (p = 0.75) or over time within the same group (time p = 0.122). Body image scores significantly decreased (reduced burden) over time for both groups (p = 0.044) and were consistently higher in the NCD vs CD group. CONCLUSIONS: Patients experienced a return to their baseline quality of life within a year of surgery. Clinicians should prioritize and improve identifying and discussing postoperative challenges such as changes in physical and social functioning and body image.

Perioperative outcomes in gynecologic pelvic exenteration before and after implementation of an enhanced recovery after surgery program.

OBJECTIVES: To compare perioperative outcomes in patients undergoing pelvic exenteration for gynecologic malignancies before and after implementation of Enhanced Recovery After Surgery (ERAS) protocols. METHODS: We performed an institutional retrospective cohort study of patients undergoing pelvic exenteration for gynecologic malignancies before (1/1/2006-12/30/2014) and after (1/1/2015-6/30/2023) ERAS implementation. We described ERAS compliance rates. We compared outcomes up to 60 days post-exenteration. Complication grades were defined by the Clavien-Dindo system. RESULTS: Overall, 105 women underwent pelvic exenteration; 74 (70.4%) in the pre-ERAS and 31 (29.5%) in the ERAS cohorts. There were no differences between cohorts in age, body mass index, race, primary disease site, type of exenteration, urinary diversion, or vaginal reconstruction. All patients had complications, with at least one grade II+ complication in 94.6% of pre-ERAS and 90.3% of ERAS patients. The ERAS cohort had more grade I-II gastrointestinal (61.3% vs 21.6%, p < 0.001) and hematologic (61.3% vs 36.5%, p = 0.030) and grade III-IV renal (29.0% vs 12.2%, p = 0.048) and wound (45.2% vs 18.9%, p = 0.008) complications compared to the pre-ERAS cohort. ERAS patients had a higher rate of ileus (38.7% vs 10.8%, p = 0.002), urinary leak (22.6% vs 5.4%, p = 0.014), pelvic abscess (35.5% vs 10.8%, p = 0.005), postoperative bleeding requiring intervention (61.3% vs 28.4%, p = 0.002), and readmission (71.4% vs 46.5%, p = 0.025). Median ERAS compliance was 60%. CONCLUSIONS: Pelvic exenteration remains a morbid procedure, and complications were more common in ERAS compared to pre-ERAS cohorts. ERAS protocols should be optimized and tailored to the complexity of pelvic exenteration compared to standard gynecologic oncology ERAS pathways.

Comparison of urological outcomes and quality of life after pelvic exenteration: partial vs radical cystectomy.

OBJECTIVE: To compare perioperative morbidity, functional and quality-of-life (QoL) outcomes in patients with partial cystectomy vs radical cystectomy as part of pelvic exenteration. PATIENTS AND METHODS: Retrospective analysis of a prospectively maintained database of pelvic exenteration patients (1998-2021) was conducted in a single centre. Study outcomes included postoperative complications, quality-of-life, functional and stoma-related outcomes. The 36-item Short-Form Health Survey Physical and Mental Health Components, Functional Assessment of Cancer Therapy-Colorectal questionnaires and Distress Thermometer were available pre- and postoperatively. QoL outcomes were compared at the various time points. Stoma embarrassment and care scores were compared between patients with a colostomy, urostomy, and both. RESULTS: Urological complications were similar between both groups, but patients with partial cystectomy experienced less wound-related complications. Overall, 34/81 (42%) partial cystectomy patients reported one or more long-term voiding complication (i.e., incontinence [17 patients], frequency [six], retention [three], high post-voiding residuals [10], permanent suprapubic catheter/indwelling catheter [14], recurrent urinary tract infection [nine], percutaneous nephrostomy [three], progression to urostomy [three]). The QoL improved following surgery in both the partial and radical cystectomy groups, differences between cohorts were not significant. Patients with two stomas reported higher embarrassment scores than patients with one stoma, although this did not result in more difficulties in stoma care. CONCLUSIONS: Partial cystectomy patients have fewer postoperative wound-related complications than radical cystectomy patients, but often experience long-term voiding issues. The QoL outcomes are similar for both cohorts, with significant improvement following surgery.

A Preliminary Phenomenological Exploration of Experiences of the Empty Pelvis Syndrome Derived From a Modified-Delphi: The Price of Survival Following Pelvic Exenteration for Advanced Pelvic Cancer.

OBJECTIVE: The empty pelvis syndrome (EPS) is common after pelvic exenteration (PE), causing fluid collections, bowel obstruction, perineal sinuses, and fistulas. The best approach to fill the pelvis to mitigate this remains controversial, and the impact of EPS on health-related quality of life (HrQoL) is unknown. This study is the first to begin to explore lived-experiences of EPS complications. METHODS: Unstructured EPS virtual focus group meetings were conducted with a convenience sample of patients who underwent PE, as an extension of a modified-Delphi study. Interpretative phenomenological analysis was conducted on verbatim transcripts to generate group experiential themes. RESULTS: Twelve patients (eight UK, one Dutch, and three Belgian) participated in four focus groups. Eight EPS complications were reported, (two pelvic collections, five chronic perineal sinuses, and one bowel obstruction). Group experiential themes were 'Out of Options', depicting patients forced to accept complications or limited survival; 'The New Normal', with EPS potentially delaying adaptation to post-PE HrQoL; 'Information Influencing Adaptation,' emphasising the significance of patients understanding EPS to cope with its effects; and 'Symptoms,' reporting manifestations of EPS, the resultant physical limitations, and an intangible feeling that patients lost part of themselves. CONCLUSIONS: EPS may influence patient decision-making, regret, adaptation, and information-seeking. It can cause a variety of unpleasant symptoms and physical limitations, which may include phantom phenomenon. This work supports ongoing purposeful HrQoL research to better define these themes.

Imaging in pelvic exenteration-a multidisciplinary practice guide from the ESGAR-SAR-ESUR-PelvEx collaborative group.

Pelvic exenteration (PE) is a radical surgical approach designed for the curative treatment of advanced pelvic malignancies, requiring en-bloc resection of multiple pelvic organs. While the procedure is radical, it has shown promise in enhancing long-term survival and is now comparable in surgical mortality to elective resections for primary pelvic cancers. Imaging plays a crucial role in preoperative planning, with MRI, CT, and PET/CT being pivotal in assessing the extent of cancer and formulating a surgical roadmap. This paper presents clinical practice guidelines for imaging in the context of PE, developed jointly by ESGAR, SAR, ESUR, and the PelvEx Collaborative. These guidelines aim to standardize imaging protocols and reporting to improve the preoperative assessment and facilitate decision-making in the multidisciplinary treatment of pelvic cancers. Our recommendations underscore the importance of a multidisciplinary approach and the need for clear and precise imaging reports to optimize patient care. CLINICAL RELEVANCE STATEMENT: Our recommendations underscore the importance of a multidisciplinary approach and the need for clear and precise imaging reports to optimize patient care. KEY POINTS: MRI is mandatory for local staging in pelvic exenteration. Structured reporting (using the template provided in this guide) is recommended. Multidisciplinary review of imaging is critical for surgical planning.

Quality of life following pelvic exenteration in neoplasms.

BACKGROUND: Pelvic exenteration (PE) is an extensive surgical treatment reserved for advanced or recurrent pelvic neoplasms, with potential impacts on patients' quality of life (QoL) poorly referenced in the literature. OBJECTIVES: This study aimed to evaluate QoL outcomes among three types of PE. METHODS: A cross-sectional study assessed 106 patients divided into anterior PE (APE), posterior PE (PPE), or total PE (TPE) groups. QoL was measured using e short form 36 version 2 (SF-36) and the European Organization for Research and Treatment of Cancer QoL Quality of Life Questionnaire Core 30 (QLQ-C30) QoL questionnaires. Descriptive and inferential analyses compared questionnaire scores. RESULTS: The findings unveiled a balance among the three groups concerning demographic variables and comorbidities, with the exception of a male predominance in the APE and TPE cohorts. Notably, the APE group exhibited elevated scores in overall health (assessed via SF-36) and social functioning and diarrhea domains (assessed via QLQ-C30). Moreover, in terms of the fatigue and nausea/vomiting domains (assessed via QLQ-C30), the APE group demonstrated superior QoL compared to the PPE group. Conversely, the PPE group manifested a notably lower QoL in the constipation domain (assessed via QLQ-C30) compared to the other two groups. Additionally, disease recurrence was significantly associated with diminished QoL across multiple domains. CONCLUSION: APE patients exhibited better QoL than PPE and TPE groups, with disease recurrence adversely affecting QoL.

Feasibility of a tailored operative strategy from organ preservation to pelvic exenteration for cT4 rectal cancer depending on neoadjuvant response.

PURPOSE: Improvements in neoadjuvant therapy for locally advanced cT4 rectal cancer have led to improved tumour response and thus a variety of suitable management strategies. The aim of this study was to report management and outcomes of patients with cT4 rectal cancer undergoing a spectrum of treatment strategies from organ preservation (OP) to pelvic exenteration (PE). METHODS: Patients who underwent elective treatment for cT4 rectal cancer between 2016 and 2021 were included. All patients were treated with curative intent. Surgical management was adapted to tumour response. Kaplan-Meier curves were generated to compare 3-year overall survival (3y-OS), local recurrence (3y-LR) and distant metastases (3y-DM) between different strategies. RESULTS: Among 152 patients included, 13 (8%) underwent OP, 71 (47%) TME and 68 (45%) APR/PE. The median follow-up was 31.3 months. Patients undergoing OP had a lower tumour pretreatment (p < 0.001). Compared to patients with TME, those with APR/PE had a higher rate of ypT4 (p = 0.001) with a lower R0 rate (p = 0.044). The 3y-OS and 3y-DM were 78% and 15.1%, respectively, without significant differences. The 3y-LR was 6.6%, and patients with OP had a significantly worse 3y-local regrowth compared to 3y-LR in patients with TME and APR/PE (30.2% vs. 5.4% vs. 2%, p = 0.008). CONCLUSION: cT4 tumours may be suitable for the full spectrum of rectal cancer management from organ preservation to pelvic exenteration depending on tumour response to neoadjuvant therapy. However, careful attention is required in OP as local regrowth in up to 30% of cases reinforces the need for sustained active surveillance in Watch&Wait programmes.

Radical resection of locally advanced and recurrent colorectal carcinoma involving major nerve resection: a systematic review of surgical, oncological and functional outcomes.

BACKGROUND: The aim of this study was to explore the surgical, oncological and quality of life outcomes in the setting of radical resection of colorectal carcinoma involving major nerve resection. METHODS: A systematic review of the literature was registered with the International Prospective Register for Systematic Reviews (PROSPERO) and performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify papers relating to outcomes in radical resection of colorectal cancer where major nerve resection was undertaken. Papers were identified from OVID Medline, EMBASE Classic and Web of Science encompassing all publications in English from January 2010 to June 2023. A total of 1357 nonduplicate studies were identified and screened for relevance, with six studies included in the final review. RESULTS: A total of 354 major nerve resections were undertaken across the six included studies. Overall postoperative morbidity was reported at rates of up to 82%. Two studies considered nerve-resection-specific oncological outcomes, with complete pathological resection achieved at rates comparable to the wider pelvic exenteration cohort (65-68%) and without any overall survival disadvantage being conveyed by major nerve resection (p = 0.78). Two studies considered functional outcomes and noted a transient decrease in physical quality of life over the first 6 months postoperatively (p = 0.041) with significant loss to follow-up. One study considered postoperative pain in nerve resection and noted no significant increase in patient-reported pain scores associated with nerve resection (p = 0.184-0.618). CONCLUSIONS: Major nerve resections in locally advanced and recurrent colorectal cancer remain understudied but with encouraging initial oncological and functional outcomes. Multicentre collaborative prospective reviews are needed to better elucidate contributors to postoperative morbidity and functional deficits and further establish interventions to ameliorate them.

Evaluating postoperative hernia incidence and risk factors following pelvic exenteration.

Pelvic exenteration (PE) is a technically challenging surgical procedure. More recently, quality of life and survivorship following PEs are being increasingly acknowledged as important patient outcomes. This includes evaluating major long-term complications such as hernias, defined as the protrusion of internal organs through a facial defect (The PelvEx Collaborative in Br J Surg 109:1251-1263, 2022), for which there is currently limited literature. The aim of this paper is to ascertain the incidence and risk factors for postoperative hernia formation among our PE cohort managed at a quaternary centre. METHOD: A retrospective cohort study examining hernia formation following PE for locally advanced rectal carcinoma and locally recurrent rectal carcinoma between June 2010 and August 2022 at a quaternary cancer centre was performed. Baseline data evaluating patient characteristics, surgical techniques and outcomes was collated among a PE cohort of 243 patients. Postoperative hernia incidence was evaluated via independent radiological screening and clinical examination. RESULTS: A total of 79 patients (32.5%) were identified as having developed a hernia. Expectantly, those undergoing flap reconstruction had a lower incidence of postoperative hernias. Of the 79 patients who developed postoperative hernias, 16.5% reported symptoms with the most common symptom reported being pain. Reintervention was required in 18 patients (23%), all of which were operative. CONCLUSION: This study found over one-third of PE patients developed a hernia postoperatively. This paper highlights the importance of careful perioperative planning and optimization of patients to minimize morbidity.

A novel classification of posterior pelvic exenteration to assess prognosis in female patients with locally advanced primary rectal cancer: a retrospective cohort study from China PelvEx collaborative.

PURPOSE: Surgical techniques and the prognosis of posterior pelvic exenteration for locally advanced primary rectal cancer in female patients pose challenges that need to be addressed. Therefore, we investigated the short-term and survival outcomes of posterior pelvic exenteration in female patients using a novel Peking classification. METHODS: We retrospectively analysed a prospective database from China PelvEx Collaborative across three tertiary referral centres. A total of 172 patients who underwent combined resection for locally advanced primary rectal cancer were classified based on four subtypes (PPE-I [64/172], PPE-II [68/172], PPE-III [21/172], and PPE-IV [19/172]) according to the Peking classification; perioperative characteristics and short-term and oncological outcomes were analysed. RESULTS: Differences were significant among the four groups regarding colorectal reconstruction (p < 0.001), perineal reconstruction (p < 0.001), in-hospital complications (p < 0.05), and urinary retention (p < 0.05). The R0 resection rates for PPE-I, PPE-II, PPE-III, and PPE-IV were 90.6%, 89.7%, 90.5%, and 89.5%, respectively. The 5-year overall survival rates of the PPE-I, PPE-II, PPE-III, and PPE-IV groups were 73.4%, 68.8%, 54.7%, and 37.3%, respectively. Correspondingly, their 5-year disease-free survival rates were 76.0%, 62.5%, 57.7%, and 43.1%, respectively. Notably, the PPE-IV group demonstrated the lowest 5-year overall survival rate (p < 0.001) and 5-year disease-free survival rate (p < 0.001). CONCLUSION: The Peking classification can aid in determining suitable surgical techniques and conducting prognostic assessments in female patients with locally advanced primary rectal cancer.

Cecum to pelvis technique: a simple and autologous solution to prevent postoperative complications in pelvic surgery.

BACKGROUND: Empty Pelvis Syndrome, subsequent to the removal of pelvic organs, results in the descent of the small bowel into an inflamed pelvic cavity, leading to the formation of adhesions and subsequent small bowel obstruction. However, no effective measures have been previously described. OBJECTIVE: Describe a simple and autologous solution to prevent "Empty Pelvis Syndrome," small bowel obstruction, and adhesions by utilizing the cecum to occlude the pelvis. DESIGN: Mobilization of the right colon to lower the cecum into the pelvic cavity to occlude the superior pelvic ring to some degree and changing the direction of the terminal ileum. SETTINGS: Hospital Universitario Fundación Jiménez Díaz, Department of General Surgery, Colorectal Service. PATIENTS: Eight anonymized patients were included in this study, each with varying colorectal pathologies. Patients were above 18 years old. MAIN OUTCOME MEASURES: Percent of blockage of the superior pelvic ring produced by the descended cecum recorded in percentage; the amount of small intestine descended past the superior pelvic ring recorded in cm. RESULTS: The mobilization of the cecum achieved partial occlusion of the superior pelvic ring. The descent of the small bowel beyond this landmark ranged from 0 to 4.9 cm. LIMITATIONS: Given the small number of patients included in this study, these results cannot be generalized to the whole of the population. A bladder emptying protocol prior to CT scans was not implemented, resulting in variations in measurements among patients. CONCLUSION: The cecum-to-pelvis technique is a simple method that can serve as an autologous solution to EPS (enteropelvic fistula) and help reduce postoperative complications such as SBO (small bowel obstruction) and adhesions. It is not essential to completely occlude the superior pelvic ring to achieve successful outcomes.

Developing a curriculum for advanced fellowship training in complex cancer for the UK.

AIM: Surgery for complex colorectal cancer is elaborate: preoperative assessment, patient selection, radiological interpretation, operative strategy, operative technical skills, operative standardization, postoperative care and management of complications are all critical components. Given this complexity, training that encompasses all these crucial aspects to generate suitably edified surgeons is essential. To date, no curriculum exists to guide training in advanced and recurrent pelvic malignancy, particularly for complex colorectal cancer. Such a curriculum would potentially offer numerous advantages, not only for individual surgeons but also for research, governance, international collaboration and benchmarking. The aim of this study was to design and develop a framework for a curriculum for fellowship training in complex colorectal cancer that encompasses pelvic exenteration surgery. METHOD: Kern described a six-step method for curriculum design that is now widely adopted in medical education. Our study utilizes steps 1-4 of Kern's method to develop a syllabus and assessment framework for curriculum development for fellowship training in complex colorectal cancer encompassing pelvic exenteration. A literature review was conducted to address step 1, followed by targeted needs assessment in step 2 by conducting focus groups with trainees, fellows and experts to identify learning needs and goals with objective setting for step 3. An expert consensus group then voted on these recommendations and developed educational strategy recommendations as step 4. For the purposes of brevity, 'pelvic exenteration' in the text is taken to also encompass extended and multivisceral resections that fall under the remit of complex [colorectal] cancer. RESULTS: Step 1 of Kern's method identified a gap in the literature on curricula in complex cancer surgery. Step 2 identified key areas regarded as learning needs by trainees, including anatomy, hands-on experience and case volume. Step 3 defined the goals and objectives of a fellowship curriculum, defined in six domains including theoretical knowledge, decision-making, technical skills, postoperative management and continuing professional development. Finally, as a prelude to stages 5 and 6, a strategy for implementation and for feedback and assessment was agreed by an expert consensus meeting that defined case volume (a minimum of 20 pelvic exenteration operations within a fellowship period) and coverage of this syllabus with derived metrics. CONCLUSIONS: Our working group has developed a curriculum framework for advanced fellowship training in complex cancer in the UK. Validation is needed through implementation, and affirmation of its utility, both nationally and internationally, must be sought.

Human factors in pelvic exenteration: themes in high-performing teams.

AIM: The aim of this study was to investigate the role of human factors in pelvic exenteration and how team performance is optimized in the preoperative, intraoperative and postoperative phases. METHOD: Qualitative analysis of focus groups was used to capture authentic human interactions that reflect real-world multiprofessional performance. Theatre teams were treated as clusters, with a particular focus group containing participants who worked together regularly. RESULTS: Three focus groups were conducted. Four themes emerged - driving force, technical skills, nontechnical skills and operational aspects - with a total of 16 subthemes. Saturation was reached by group 2, with no new subthemes emerging after this. There was some interaction between the themes and the subthemes. Broadly speaking, driving force led to the development of specialised technical skills and nontechnical skills, which were operationalized into successful service through operational aspects. CONCLUSION: This study of teams performing pelvic exenteration is the first in the field using this methodology. It has generated rich qualitative data with authentic insights into the pragmatic aspects of developing and delivering a service. In addition, it shows how the themes are connected or 'coupled' in a network, for example technical and non-technical skills. In a complex system, 'tight coupling' leads to both high performance and adverse events. In this paper, we report the qualitative aspects of high performance by pelvic exenteration teams in a complex sociotechnical system, which depends on tight coupling of several themes.

Variation in outcome measurement and reporting in studies of pelvic exenteration for locally advanced and recurrent rectal cancer: a systematic review.

AIM: There is increasing research interest in pelvic exenteration for locally advanced and recurrent rectal cancer. Heterogeneity in outcome reporting can prevent meaningful interpretation and valid synthesis of pooled data and meta-analyses. The aim of this study was to assess homogeneity in outcome measures in the current pelvic exenteration literature. METHOD: MEDLINE, Embase, CENTRAL, CINAHL and Scopus databases were searched from 1990 to 25 April 2023 to identify studies reporting outcomes of pelvic exenteration for locally advanced or recurrent rectal cancer. All reported outcomes were extracted, merged with those of similar meaning and assigned a domain. RESULTS: Of 4137 abstracts screened, 156 studies met the inclusion criteria. A total of 2765 outcomes were reported, of which 17% were accompanied by a definition. There were 1157 unique outcomes, merged into 84 standardized outcomes and assigned one of seven domains. The most reported domains were complications (147 studies, 94%), survival (127, 81%) and surgical outcomes (123, 79%). Resection margins were reported in 122 studies (78%): the definition of a clear resection margin was not provided in 45 studies (37%), it was unclear in 11 studies (9%) and not specified beyond microscopically 'clear' or 'negative' in 31 (28%). Measurements of 2, 1, 0.5 mm and any healthy tissue were all used to define R0 margins. CONCLUSION: There is significant heterogeneity in outcome measurement and reporting in the current pelvic exenteration literature, raising concerns about the validity of comparative or collaborative studies between centres and meta-analyses. Coordinated international collaboration is required to define core outcome sets and benchmarks.

IMPACT organizational survey highlighting provision of services for patients with locally advanced and recurrent colorectal cancer across Great Britain and Ireland.

AIM: Locally advanced and recurrent colorectal cancer represents a complex clinical entity, which requires multidisciplinary decision-making and management. The aim of this work is to understand the provision of clinical services in this cohort of patients across Great Britain and Ireland (GB&I) as a key essential step to help facilitate future service development and improvement. METHOD: A cross-sectional, organizational survey was sent to all colorectal cancer multidisciplinary teams (MDTs) across GB&I. It consisted of 12 key questions addressing the provision of specialist services and advanced surgical techniques. Results are reported in line with the CHERRIES guideline. RESULTS: One hundred and seventy-five MDTs across GB&I participated, with 142 English, 13 Welsh, 14 Scottish, 3 Northern Irish and 3 Irish MDTs. The overall response rate was 93.5% (175/187). Ninety (51.4%) hospital sites reported having a specialist dedicated or subsection MDT. Specialist advanced nursing support was available in 46 (26.2%) hospitals, with a dedicated advanced colorectal cancer outpatient clinic available in 31 (17.7%) hospitals. One hundred and thirteen MDTs (64.5%) offered surgery for advanced colonic cancer, 82 (46.8%) for recurrent colonic cancer, 58 (33.1%) for advanced rectal cancer and 39 (22.2%) for recurrent rectal cancer. A variable number of MDTs offered specialist surgical techniques, including distal sacrectomy [33 (18.9%)], high sacrectomy [16 (9.1%)], complex vascular resection ± reconstruction [33 (18.9%)] and extended lymphadenectomy (pelvic sidewall or para-aortic) [44 (25.1%)]. CONCLUSION: The IMPACT organizational survey highlights the current variation in the delivery and provision of clinical services for patients with advanced and recurrent colorectal cancer across Great Britain and Ireland.
